[R-sig-ME] Resume terminated lmer fit if verbose=TRUE?

[Doran, Harold]

Yes. See ?lmer and the start argument. You can provide the function with starting values, which can come as the last iteration of the output from verbose. 100 hours is a ridiculous amount of computing time. 

You might want to check your model and make sure it isn't overparameterized.
